The JENSEN CD-660 is a portable Bluetooth digital music system with a CD player, designed for versatile audio playback. It combines traditional CD playback with modern Bluetooth connectivity, USB playback, FM radio, and an auxiliary input, offering a comprehensive audio experience. The unit is designed for ease of use, with clearly labeled controls and a compact form factor that includes a carrying handle for portability.

Function Description

The CD-660 serves as a multi-source audio player. Its primary functions include:

CD Playback: The device features a top-loading CD door for playing commercial audio CDs. It also supports playback of self-compiled CD-R/CD-RW discs, including MP3 CDs. The CD player offers standard controls such as play, pause, stop, skip, and search. It also includes repeat modes (repeat 1, repeat all, repeat folder for MP3 CDs) and a program play mode, allowing users to create a custom sequence of up to 20 tracks. The LCD display shows the current track number, total tracks, and track time during CD playback.
Bluetooth Connectivity: The CD-660 can wirelessly connect to Bluetooth-enabled devices such as smartphones, tablets, and computers. This allows users to stream music from their devices to the CD-660's speakers. The pairing process is straightforward, involving selecting Bluetooth mode on the unit and connecting from the external device. The unit indicates successful pairing with a steady Bluetooth icon on the LCD display. It also supports re-pairing with other devices.
USB Playback: The unit is equipped with a USB port, enabling playback of music files stored on USB flash drives. It supports MP3 files and displays folder and track information on the LCD. Similar to CD playback, USB mode offers play, pause, stop, skip, search, and repeat functions (repeat 1, repeat all, repeat folder).
FM Radio: The CD-660 includes an FM radio tuner, allowing users to listen to their favorite radio stations. It supports both manual and automatic tuning. Up to 30 FM stations can be manually preset for quick recall. An extendable FM antenna is provided for optimizing reception. The LCD display shows the current FM frequency.
Auxiliary Input (AUX IN): An AUX IN jack allows for wired connection of external audio sources, such as iPods, MP3 players, or other digital audio devices. This provides flexibility for playing music from devices that do not support Bluetooth.
Recording (Encoding to MP3): A unique feature of the CD-660 is its ability to record audio from various sources (Bluetooth, CD, FM Radio, AUX IN) directly to a connected USB device. The recording is saved as an MP3 file (128 kbps/32khz) in a dedicated "REC" folder on the USB drive.
Headphone Output: A headphone jack is included for private listening, automatically muting the speakers when headphones are plugged in.

Usage Features

The CD-660 is designed with user convenience in mind, featuring a clear control layout and intuitive operation:

Power Control: A single SOURCE button manages power on/off and mode selection. Tapping it cycles through available modes (Bluetooth, CD, USB, FM Radio, AUX), while pressing and holding it turns the unit off.
Volume Control: Dedicated VOLUME - / + buttons allow for easy adjustment of the listening level.
Navigation and Playback Controls: Standard playback buttons (Play/Pause, Stop, Skip/Search, Folder + / +10) are provided for controlling CD, USB, and Bluetooth audio.
Radio Presets: PROG/MEM and M- / M+ buttons facilitate programming and recalling FM radio stations.
LCD Display: A clear LCD display provides visual feedback on the current mode, track number, track time, radio frequency, and other operational indicators (e.g., "bt" for Bluetooth, "Cd" for CD, "USb" for USB, "AU" for AUX, "REP" for repeat modes, "PROG" for program mode, "REC" for recording).
Portability: The unit can be powered by either an AC adapter or 6 'C' size batteries, making it suitable for both home and on-the-go use. A carrying handle is integrated for easy transport.
Safety Features: The device includes safety warnings regarding laser exposure during CD operation and recommendations for safe listening levels to protect hearing.

Maintenance Features

Maintaining the CD-660 is straightforward, focusing on general cleanliness and proper handling:

Cleaning: The unit should be cleaned with a soft, damp cloth and allowed to dry completely. Abrasive cleaners, brushes, or metallic utensils should be avoided to prevent damage to the surfaces. The radio should not be immersed in water.
CD Lens Care: For optimal CD playback, a CD-lens cleaning disc can be used to clean the lens if intermittent sound occurs.
Battery Management: When the unit is not in use for extended periods, batteries should be removed to prevent leakage. All batteries should be replaced at the same time, and mixing old and new or different types of batteries should be avoided.
Power Adapter Care: The AC adapter should be unplugged when the unit is not in use for long periods or during lightning storms.
Furniture Protection: The unit is equipped with non-skid rubber feet. To prevent potential marks or stains on fine wooden furniture, it is recommended to apply small self-adhesive felt pads to the bottom of these feet.
Storage: The unit should always be stored in a dry and clean place.
Troubleshooting Guide: A comprehensive troubleshooting guide is included in the manual to help users resolve common issues, such as no sound, CD skipping, or Bluetooth connection problems. This guide offers possible causes and solutions, and provides contact information for technical support if needed.
